Add manpage, provided by Marcos Talau (#78)

See issue #78 for the original zipfile.

I'm adding only the man page file itself, not the original `.txt` file
and the shell script to convert it using `txt2man`. The idea here is
having less dependencies. There's also man page editors out there for
future updates.

+.SH DESCRIPTION
+\fBsedsed\fP can debug, indent, tokenize and HTMLize sed scripts.

+revealing all the magic sed does on its internal buffers.
+.PP
+In indent mode, the script is reformatted with standard spacing.
